Conversion of string array to number array in javascript

Question

I have the following string

salesdata=[[0],[0],[0.767],[1.366],[2.003],[15.128],[32.766],[57.225],[0],[0],[0],[0]];

I want to convert it to an integer array with the same format of brackets to pass as highcharts input. I tried this

var data=salesdata.split(",");

You can use JSON.parse() to convert that string array to actual array type.

console.log(JSON.parse(salesdata))

You can use eval() to convert that string array to actual array type. But note that eval() is highly discouraged to use in the code.

var salesdata=`[[0],[0],[0.767],[1.366],[2.003],[15.128],[32.766],[57.225],[0],[0],[0],[0]]`;
console.log(eval(salesdata));

Assuming your salesdata is of the below format:

    var salesdata='[[0],[0],[0.767],[1.366],[2.003],[15.128],[32.766],[57.225],[0],[0],[0],[0]]';

You can convert it to integer using,

    var salesdata_array = JSON.parse(salesdata);
    console.log(salesdata_array[0])
